FiRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 701,094, dated May 27,1902.

Application filed May 2, 1901- Serial No. 58,417. (No model.) 7

To all whom it puny concern:

Be it known that We,JULIUSSETBAOKEN and PETER J. SETBAOKEN, citizens ofthe United States, and residents of Oynthiana, in the county of Poseyand State of Indiana, have invented a new and Improved Fire-Escape, ofwhich the following is a full, clear, and exact description.

This invention relates to a fire-escape of that class in which a line orrope is provided for the descent of a person, and this rope is used inconnection with certain governing mechanism for causing it to be paidout at a uniform rate.

This specification is a specific description of one form of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a sectional View showing the invention applied to abuilding. Fig. 2 is a plan View of the parts in operating adjustment.Fig. 3 is a detail perspective view showing one of the truss-sectionswhich are employed in connection with the outrigger.

Fig. 4 is an enlarged section of the governor mechanism. Fig. 5 is asection on the line 5 5 of Fig. 4. Fig. 6 is a section on the line 6 6of Fig. 4, and Fig. 7 is a sectional elevation on the line 7 7 of Fig.4.

The mechanism is mounted in a suitable framing comprising a box 8,carrying the governor mechanism, and a box 9, carryinga reel 10, overwhich is wound the rope 11. The box 9 has two of its walls, which areindicated at 12, connected together by ahinge, as indicated at 14. Thesewalls 12 form an outrigger, which is connected by a hinge to thestationary walls of the box 9, as indicated at 15. The walls 12 arecapable of folding inward, as shown by full lines in Fig. 1, or of beingthrown outward, as indicated bydotted lines, in which position theoutrigger-walls extend through the window and project out from the wallsof the building for a purpose which will appear hereinafter. Applied toeach of the walls 12 of the box 9 are two truss-sections 16, which arefastened rigidly to their respective walls 12 and which are providedwith interlocking laterally-projected flanges 17.

(Best shown in Fig. 3.) When the walls 12 are thrown outward to lie inthesame plane, thefianges 17 engage together in pairs, and then thesections 16 form trusses which strengthen the Walls 12 and cause them toretain a rigid connection, thus forming the outrigger, which serves tocarry the rope 11 clear of the walls of'the building and prevent personsdescending on the fire escape from striking said walls. The rope 11 isled from the drum 10 over a roller 18, arranged at the inner end of theoutrigger, and under a guide 19, arranged adjacent to said roller. Therope 11 then passes over a roll 20, arranged at the outer end of theoutrigger, on which roll 20the rope is held by means of a guide-plate21.

As shown bestin Fig. 4, the reel 10 is mounted at one end on astub-shaft 22, fastened to one of the stationary side walls of the box9, and the other end of the reel is fastened to a shaft 23, which ismounted loosely in a bearing 24, carried in the opposite side wall ofthe box 9. A spring 25 is arranged around a longitudinal extension 26 ofthe stub-shaft 22 and connected, respectively, with the stubshaft andwith the reel 10. This spring 25 is of such character as to permit thereel to unwind sufllciently to lower the person escaping from thebuilding to the ground, and then when the weight of such person isremoved from the rope the spring 25 will assertitself and rewind therope on the drum. In this connection we would explain that it would beadvisable that the descending end of the rope be connected with a slightcord, which may be held by a person on the ground, so as to prevent thespring 25 from running away with the rope and winding it in tangledcondition on the drum.

The shaft 23 projects into the box 8 and Fig, 1.

a stub-shaft 31, carried by one of the walls of V the casing 8.Pivotally mounted on the clutch member 29 are centrifugally-actuatedgovernor-arms 32,whi ch are provided with brakefingers 33, arranged tobear on the outer periphery of the stub-shaft 31 when the arms 32 arethrown outward upon the revolution of the clutch member 29. Springs 34are connected with the governor-arms 32 and tend to throw them inward toinactive position. As the reel 10 unwinds the clutch member 29 is turnedtherewith, and as soon as this clutch member acquires suificient speedto overcome the action of the springs 34 the brake-fingers 33 engage thestub-shaft or stationary brake member 31, and thus the action of thereel is retarded. It will be seen that this mechanism will effectivelygovern the movement of the reel and prevent it from unwinding at adangerous rate of speed.

- In using the invention the parts when inactive are arranged as shownby full lines in Should a person desire to descend,

I; the movable walls 12 of the box 9 should be thrown outward, asindicated by dotted lines in Fig. l, to form the outrigger. The persondescending should then grasp the outer end of the rope. If desired, therope may be provided with a sling or harness in which aperson may becomfortably and securely seated, and in practice we will fit theapparatus with such a device. As soon as the Weight of the person isplaced on the rope 11 the reel 10 will unwind against the spring 25, andthen as the reel revolves sufficiently fast the governor will be throwninto action and the descent of the person regulated. When the personreaches the ground, the rope 11 will be automatically rewound for asecond ascent. As mentioned above, a slight line or cord attached to therope may be used for preventing the rope from rewinding too rapidly andavoid the liability of its becoming tangled on the reel.

Various changes in the form, proportions, and minor details ofourinvention may be resorted to without departing from the spirit andscope of our invention. Hence we consider ourselves entitled to allsuchvariations as may lie within the scope of our claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. In a fire-escape, the combination with areel and means for regulating the movement thereof,of an outriggercomprising two hingeconnected sections, and truss members fastenedrespectively to the sections and having interlocking parts, for thepurpose specified.

2. The combination of two hinge-connected sections, and truss-sectionsfastened respectively to said hinge-connected sections, thetruss-sections having interlocking parts to hold the hinge-connectedsections rigid when extended.

3. In a fire-escape,the combination of a box having two of its sidewalls connected together by a hinge and one of said walls beingconnected by a hinge to the body of the box, a drum and regulatingdevices mounted in the box, a rope carried on the drum and guided overthe hinge-connected walls thereon when said walls are thrown outward,and truss-sections respectively carried on the hinge-connected sectionsof the box, said truss-sections having interlocking parts connectedtogether when the hinge-connected walls of the box are thrown into theextended position.

4. Thecombination of adrum,arotary shaft carrying it,a dog-carrierfastened to the shaft, a dog mounted on the carrier, ashaft mountedstationary in alinem cut with the rotary shaft, a clutch member loose onthe stationary shaft and inclosing the dog-carrier and dog, said dogworking with the interior of the clutch member, weighted arms pivoted onthe clutch member, and having brake-fingers, a stationary member formingabraking-surface with which the brake fingers coact, and springsactuating the weighted arms to hold them yieldingly against centrifugalmotion.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
